SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
This is then fragmented into a series of fixed-size TS Packets (i.e. link-layer frames
of 188 bytes). This is displayed in Figure 58.
Figure 65 - MPE Encapsulation of IP Packets
MPE encapsulates network-layer packets in a way that resembles the control-
plane SI tables used in a DVB network. This design can utilise existing processing
logic developed for handling the control plane functions.
At the encapsulator, each subnetwork data unit initially starts at the beginning of a
TS Packet, with the last TS packet being padded to its end. This is done to prevent
jitter when a timeout is detected. Refer to Figure 66.
